Drain cleaning for Pomona homes and rentals
Pomona has a wide mix of housing, from older bungalows near the historic districts to apartment buildings and newer tract homes, and drain trouble looks different in each. In an older house, a main line of clay or cast iron may have roots or scale inside. In a multi-unit building, one stopped branch can back up the unit at the bottom of the stack. Sorting out which case you have is the first job.
A cable run through a cleanout clears most clogs in a single branch. When several fixtures slow at once, or the same line stops again soon after clearing, the plumber looks inside with a camera and chooses between jetting, a spot repair and replacing the damaged piece. The sorting of these jobs is laid out under a clogged drain.
Water heater installation in Pomona, and why it takes a permit
Pomona's Building and Safety Division publishes a plumbing permit handout that lists what needs one: new drain, waste or vent piping, new or altered gas lines, new or relocated fixtures, and any new, replacement, relocated or altered water heater. Dishwashers are on that list too. The same handout carves out an exemption for stopping leaks in drain, soil, waste or vent pipe, with exceptions when a trap or valve is involved.
What that means for a replacement
If your tank has failed, the replacement is a permit job. A plumber who pulls it also schedules the inspection, so the work is on record when the house is sold. Before you buy, decide whether to stay with a tank or move to tankless, which changes the gas line and venting. Installation is covered at a new water heater.
The city building office is at 505 S. Garey Avenue and its main line is (909) 620-2371. The city's water report lists City Hall hours as Monday through Thursday, with Friday closed, so schedule any permit questions with that in mind.

Water supply and hardness in Pomona
The City of Pomona operates a municipal water utility, the Water Resources Department. In its 2022 Annual Water Quality Report the city says about 68 percent of its water comes from groundwater and about 25 percent is bought from the Metropolitan Water District of Southern California and Three Valleys Municipal Water District. A mix like that means the taste and mineral content of what comes out of your tap can shift with the source.
The reports on the city website are where to look for the utility's own numbers. This page states no hardness value because none was verified. Call the Water Resources Department at (909) 620-2251 and ask for the current hardness before choosing a softener, and test your own tap if you want to know what reaches your fixtures. If scale is building on faucets or inside the water heater, it is worth a conversation about treating hard water.
Sewer, leaks, repiping and water damage in Pomona
A sewer line problem is traced with a camera, and a leak is traced by closing valves and watching the meter. Water damage work here means removing standing water and drying the structure; rebuilding is a separate trade. Repiping is the answer when old supply pipe fails in many places, and the leak detection page and repiping page explain how to tell. In a multi-unit building these calls often start with one tenant noticing a stain, so the first step is finding which unit's supply or drain is the source. Look at repairing the sewer line, leak detection and repair and failing pipe repair for the details of each.
Tankless water heaters and water damage cleanup are each handled as their own service, with a page of detail apiece.
Also handled in Pomona
Fixture repair, garbage disposals, gas lines, slab leak repair, water line replacement and water softeners are all part of the same call-in, and each has its own page. Commercial plumbing for small shops and offices is available as well.
Where Pomona differs is the permit structure. Because the city treats new fixtures and water heaters as permit work, a plumber who tells you a job needs no permit should be able to explain why. Ask the question. The answer tells you how careful the plumber is about the paperwork that stays with the property.
Pomona also has a large student and rental population around Cal Poly Pomona and Western University, and tenants are often the ones who notice the problem first. A tenant can describe the symptom to the dispatcher, but repairs that change the pipes generally need the owner to agree, so it helps to have the owner's contact on hand when you call.
